Just looked at the Pennzoil site and you can now click on the weight of the oil and the specifications come up, right down to the NOACK %. Ultra and Platinum only after looking further...........
Thanks for the post. The Ultra/Platinum comparison is still odd: in the xxw-20 weights at least, Ultra is on the thickish side, Platinum on the thin. And Platinum's Noack is materially lower than Ultra's, despite being a "lesser" oil in Pennzoil's hierarchy. Makes you wonder if they were designed by the same group.

Could you post a link to the web page that shows the info?
